Re: StarTools 1.9 Beta

Small update with some bug fixes, UI fixes and getting rid of (hopefully) the last "UNKNOWN" log entries. :)

Re: StarTools 1.9 Beta

Hmmm... Yeah. That's not exactly intuitive. Will fix! Thanks, Ivo. :thumbsup: Not a priority of course, especially now that I (and hopefully others?) have a bit better understanding of what Bin is wanting to do for us here. Just something for the list of UI tweaks on the path to the final 1.9. Now ...

Re: StarTools 1.9 Beta

Hi Mike, I think this is expected behavior, and should only happen if you have chosen an integer binning mode. In that case, there are only specific "sweet spot" percentages that allow for an integer factor bin. Is that what's happening? Hi Ivo. I'll give a qualified -- aha! This starts to explain ...

Re: StarTools 1.9 Beta

I think this has been here a little while, but I usually don't run across it much as I tend to just accept preset buttons -- In Bin, there is unusual and erratic behavior of the image sizing slider. This affects use of the side +/- buttons whether clicked or hovered and mouse wheeled, as well as mo...

Re: Star Tools closes immediately on file open

I'm not sure I have come across this issue before...
Does the non-GPU version work as expected?

Please note that Linux users, will require zenity and wmctrl installed on their system. Can you confirm these packages are available on your system?

Thank you,

Re: StarTools 1.9 Beta

Hi all, I just released a new beta version. I finally found the issue causing the outsized ringing due to apparent non-linearity. I was being a... not so smart person. :roll: The issue was, that I was not taking into account the effect that synthetic luminance generation has on overexposing star cor...

Re: Journal paper on spatially variant deconvolution?

More integration (oh noes!). This of course helps the base underlying linear data. Shorter subs to prevent saturation of cores, also thus linear state. Though I have used datasets with plenty of blown cores that SVD doesn't seem bothered with at all. Odd. That's great to hear, as that is usually a ...

Re: StarTools 1.9 Beta

It's indeed an interesting failure case for the de-ringing. I will have to do some troubleshooting to see what is happening here, but it appears the issue is some sort of extreme non-linear response in the troublesome stars. Similarly odd, is a complete lack of overexposure anywhere - it may be that...

Re: Journal paper on spatially variant deconvolution?

Thanks Ivo. I've been following along. I notice you mentioned that SVD is not really meant for "fixing" star shapes, and was wondering if you could expound on that for us. :?: I know we do have a spatial error slider (I'm not very practiced with it), and you've also mentioned before that adding ite...

Re: Journal paper on spatially variant deconvolution?

Thanks for the explanation, Ivo. Of course you saw it early. The deconvolution community must be pretty small. I don't think there's so much of a community , but you can't help but be exposed to other people's work when you're researching and tinkering. I don't really move in academic circles eithe...
